DETAILED DESCRIPTION

While this invention is susceptible of embodiment in many differentforms, there is shown in the drawings and will herein be described indetail specific embodiments, with the understanding that the presentdisclosure of such embodiments is to be considered as an example of theprinciples and not intended to limit the invention to the specificembodiments shown and described. In the description below, likereference numerals are used to describe the same, similar orcorresponding parts in the several views of the drawings.

The terms “a” or “an”, as used herein, are defined as one or more thanone. The term “plurality”, as used herein, is defined as two or morethan two. The term “another”, as used herein, is defined as at least asecond or more. The terms “including” and/or “having”, as used herein,are defined as comprising (i.e., open language). The term “coupled”, asused herein, is defined as connected, although not necessarily directly,and not necessarily mechanically. The term “program” or “computerprogram” or similar terms, as used herein, is defined as a sequence ofinstructions designed for execution on a computer system. A “program”,or “computer program”, may include a subroutine, a function, aprocedure, an object method, an object implementation, in an executableapplication, an applet, a servlet, a source code, an object code, ashared library/dynamic load library and/or other sequence ofinstructions designed for execution on a computer system.

The term “program”, as used herein, may also be used in a second context(the above definition being for the first context). In the secondcontext, the term is used in the sense of a “television program”. Inthis context, the term is used to mean any coherent sequence of audiovideo content such as those which would be interpreted as and reportedin an electronic program guide (EPG) as a single television program,without regard for whether the content is a movie, sporting event,segment of a multi-part series, news broadcast, etc. The term may alsobe interpreted to encompass commercial spots and other program-likecontent which may not be reported as a program in an electronic programguide.

Reference throughout this document to “one embodiment”, “certainembodiments”, “an embodiment” or similar terms means that a particularfeature, structure, or characteristic described in connection with theembodiment is included in at least one embodiment of the presentinvention. Thus, the appearances of such phrases or in various placesthroughout this specification are not necessarily all referring to thesame embodiment. Furthermore, the particular features, structures, orcharacteristics may be combined in any suitable manner in one or moreembodiments without limitation.

The term “or” as used herein is to be interpreted as an inclusive ormeaning any one or any combination. Therefore, “A, B or C” means “any ofthe following: A; B; C; A and B; A and C; B and C; A, B and C”. Anexception to this definition will occur only when a combination ofelements, functions, steps or acts are in some way inherently mutuallyexclusive.

As used herein, the term Triggered Declarative Object (TDO) is adownloadable software object created by a content creator or serviceprovider. Generally, such objects have declarative content (text,graphics, scripts, and audio) whose function and behavior is tied insome way to the television programming that it accompanies. The TDO, inexamples shown herein, are pushed from a service provider in advance ofa time defined by a trigger object or multiple trigger objects (asexplained below) so that the TDO is available when the trigger arrives.Various standards bodies may define associated available behaviors,appearance, trigger actions, and transport methods for content andmetadata for a TDO. Additionally, requirements regarding timing accuracyof TDO behaviors relative to audio/video may be defined by standardsbodies.

As used herein a “trigger” or “announcement trigger” is a data object,bound to a particular program segment, that references the locationwhere a TDO may be acquired, such as a file name or identifier for afile that has already been downloaded via non-real-time (NRT) services.Requirements regarding timing accuracy of triggers relative toaudio/video may also eventually be dictated by standards bodies. CertainTDOs will only make sense in conjunction with a certain program. Anexample is a TDO that collects viewer response data, such as voting on agame show or contest.

The following examples illustrate several of the many potential uses forTDOs:

Personalized Stock Portfolio Display using Available Screen Real Estate

In this example, the user initializes this TDO with a list of the stocksof interest (those that should be displayed when the TDO is running) Ifthe user chooses to activate the “My Portfolio” TDO, it displays itselfin an area of the screen designated by the service provider as“available screen real estate.” The TDO responds appropriately by hidingitself if the screen space becomes unavailable (for example, due to anadvertisement or other scene change). This example makes clear that thesignaling inserted by the broadcaster, that supports the TDO, involvessynchronization both as to timing (to accommodate advertising segments)as well as spatially (to adjust to a variety of screen layouts of thebroadcast programming)

Car Race TDO Example

TDOs can be used to enhance the experience of watching a televised carrace. An example user scenario follows: When an ATSC 2.0-capable DTVreceiver to the NASCAR race, the user discovers that an interactivefeature is available. He activates the “Favorite Driver Watch” TDO,which offers him a choice of which driver to monitor. He chooses hisfavorite. The TDO then shrinks in size to occupy a small portion of thescreen, and displays a thumbnail photo of the driver, his current speed,RPM, and position in the race. The TDO can be programmed to disappearduring advertising spots and whenever racing is suspended or complete.

Voting TDO

Some programs involve viewer participation in the form of voting forfavorite performers or other types of viewer feedback. A TDO can be usedto capture the same kind of viewer input that a telephone call to aparticular number can register. A TDO could be activated in this case todeliver a viewer's vote for his favorite performer. Where user choicesare involved, especially in the case of multiple choices, methods ofassociating particular buttons on a remote control with matching shapesand/or colors in on-screen instructions have proved helpful in otherconsumer contexts and may be of benefit in enhancing the interactiveuser experience.

Baseball Game TDO

A user setup mode would allow the viewer to choose a favorite player orteam to monitor. The TDO can then provide updated statistics and otherinformation. The TDO may be associated with a particular broadcast of abaseball game.

Pizza Delivery TDO

By way of a further example, consider a sporting event that is televisedand sponsored by a pizza delivery company. The TDO can be a program thatpermits the user to order a pizza via his or her television set. The TDOcan be pre-delivered and whenever the pizza delivery company has acommercial, a trigger announcement can be presented to the viewer. Byway of example, consider an announcement of rotating large text thatsays “CLICK ENTER TO ORDER A PIZZA NOW!”. The user can then select<ENTER> from the remote control and enable the TDO which collects theuser's address (either from pre-stored information) or by entry of theuser's telephone number or other identifier. A menu can then bepresented that permits selection of a type of pizza, quantity and otherrelevant information. The user can then place the order and possiblyeven pay for the order online using the TDO.

These examples and others presented above are but a few of thepossibilities that can capitalize on the time association of the TDOwith programming or commercial content. Upon consideration of theseteachings, those skilled in the art will appreciate that many variationsare possible and that the TDOs can be programmed to provide a variety oftimely information, products and services to the user. Generallyspeaking, a TDO can carry out any function that one can implement bysoftware programming that can run on a television receiver deviceprocessor platform—present or future.

In most cases a user interacts with the receiver initially to launch oractivate one or more TDOs that may accompany a given program. One couldenvision a receiver implementation in which any TDO that has beendownloaded is immediately launched as soon as the timing is right withinthe program. Users, however, probably would find this intrusive.Therefore, a more subtle method is needed that will notify the user thatan enhanced (interactive) experience is being offered. A graphical iconor other visual indicator (e.g., an animation) can be displayed in acorner of the screen, for example, to indicate the availability of a TDOoffering interactivity. The user may then push a button on the remotecontrol to launch the TDO.

In accord with the present subject matter, triggers carrying specificmetadata allow a TDO to signal to the user of an Internet-connected TVthat interactive content synchronized to the current programming can beenabled for interaction. The receiver may respond by creating anon-screen display based on the metadata as an “announcement indicator.”If the user enables display of such announcements, then text and/orgraphics (stationary or moving, possibly accompanied by audio) can bedisplayed notifying the user that a TDO is available for interaction. Ifthe user cares to interact with the TDO, then the TDO is launched andenabled for user interaction upon user command.

This concept gives broadcasters some control over the way TDOs areannounced. The icon or graphic associated with one broadcaster's TDOsmay be unique and easily identifiable to the viewer, as compared withsimilar announcements associated with a different broadcaster'sprograms. Announcements are done in a manner that does not interrupt theviewing experience in any significant way. The present subject matterprovides a method for the content creator to control the way a TDOannounces its availability. The user retains the option to decidewhether or not to allow any announcement of available TDOs and alsowhether or not to interact with each available TDO.

In certain implementations consistent with the present embodiments, thedefinition of the synchronized TDO includes a definition for itsbehavior prior to being activated, e.g. when the trigger indicates thatthe timing is appropriate for it to be activated. Prior to beingactivated, the TDO may announce itself as a small graphical icon orother announcement. The user knows that when such icons or announcementsare on-screen, pushing an appropriate button on the remote will launchthe TDO. The TDO trigger's metadata describes the characteristics andbehavior of the TDO and the time period it is available. The pre-launchappearance may be a textual message such as “to Interact with thisprogram hit <ENTER>,” or it may be a static or animated icon or graphic,or some combination of the two.

While widget functions were envisioned as general purpose functions suchas stock quotes, weather, photo viewing, news and info, and the like,TDOs take the concept farther by virtue of their being associated withtelevision program content. Metadata sent along with the audio/video ofthe program determines the behavior and functionality of the TDO. Theconcept of a synchronized trigger (or multiple triggers for a singleTDO) enables user interaction during a program. In the alternative, aTDO may be self triggering and may hence not require a separate triggerobject.

In the above polling example, a program provider conventionally displaysa screen that states, “To vote, please text or call” and a telephonenumber. Rather than doing this, the trigger may be used to announce thata TDO can be enabled to provide the polling interaction, withoutrequiring the program to cut away to a screen as described above. Theuser reads the text or graphics derived from the trigger metadata anddecides whether or not to launch the TDO. If the TDO is launched, thetrigger data is used to determine the screen location the TDO (asdesigned by the programmer), which can be displayed without interruptingor blocking the scene. The TDO may also have the capability of recordingthe polling data and reporting back through an Internet connection ifavailable. If an Internet connection is not available, the TDO mayannounce how to do the polling in an alternate method. In addition toTV, this concept can be applied to mobile phones, as well as cable,satellite, and IPTV services.

Turning now to FIG. 1, an example implementation of a system utilizingTDOs in a manner consistent with the present embodiment is depicted witha service provider 10 supplying television content over a network 14(wired or wireless) such as a cable television network, Internet,broadcast or satellite network. The content may be delivered directly toa TV set 20, or may be delivered via a set top box (STB) decoderterminal 24. The television (and STB) may be controlled using a remotecontroller device such as 30. The service provider 10 may be a multipleservice operator (MSO) as shown that provides both digital television(DTV) program signals as well as Internet services in certainimplementations.

In this example illustration, the service provider 10 pre-delivers theTDO to the television set 20 using non-real time (NRT) services inadvance of when the TDO will be announced and in advance of when it willbe launched. This can be accomplished using the DTV signal by use of anInternet connection to the television. The TDO is then initialized ifany initialization is needed and resides in storage of the television 20(or alternatively in the STB) until it is announced. The TDO may be selftriggered so that it launches at a specified time or may be triggeredlater by a trigger object as will be described.

The TDO, as noted above, is a software program that can carry out adesignated function associated with either the TV program being watched,a particular time of day, a television commercial, or other association.Once downloaded to the television 20, the TDO waits until a triggersignal combined with a user action activates the TDO.

In this figure, the presence of a TDO is announced at an appropriatetime during programming. This announcement can take many forms includingthe simple icon 50 shown as a box enclosing a question mark. However,the announcement is defined by a software routine forming a part of thetrigger signal or more preferably programmed into the logic of the TDOitself. The announcement can, therefore, be anything that the programmerenvisions including any combination of still or animated icons, audio,text images, graphics or other announcements. The user can then activatethe associated TDO by executing an appropriate command from the remotecontroller 30. Upon the TV's receipt of the appropriate command, the TDOis launched.

In general, the trigger object supplies the timing and screen locationfor the announcement in the preferred implementation, and the TDO itselfdefines what to do when triggered. Sometimes a small amount of data inthe trigger object may be involved. For example, in case of displayscreen real estate, the trigger may also include data (such as thecoordinates of the available screen real estate) that is used todetermine the location that an announcement defined by the TDO is to beplaced. The TDO itself preferably contains the announcement definitionbecause the TDO preferably defines everything to do with its ownappearance and behavior. Of course, in other implementations, thetrigger object can also contain to have other data.

The trigger signal includes data that may define any of the followingattributes associated with the TDO:

-   -   A TDO identifier or other mechanism for linking a trigger object        with its associated TDO;    -   Screen location for at least a portion of the TDO;    -   Time that the TDO expires (or time window or windows in which        the TDO can be activated);    -   An instruction to start, end or suspend a TDO operation;    -   Announcement definition (e.g., code or data that generates an        icon or generates an animation—but this is preferably defined in        the TDO);    -   Script for generation of announcement, graphics or text—but this        is also preferably defined in the TDO;    -   Screen location for the Announcement;    -   At least one time at which the announcement is to be presented        to the viewer—such time may be the time of receipt of the        trigger or may be a defined time in the future;    -   Other attributes of TDO or trigger announcement;

Alternatively, the TDO itself may include all aspects of operation thatare not timing dependent, such as the script for generation ofannouncement, graphics or text, the code that defines the announcement,and the default screen location where the TDO and announcements are toappear.

Referring now to FIG. 2, an example process 100 is depicted starting at104 in which an initialization phase or configuration phase orreconfiguration phase is entered. In this phase, at 108, the user candetermine if he or she wishes to interact with TDOs, since some usersmay consider TDOs to be a disruption of their program viewing experienceor otherwise may not wish to interact with TDOs. If the user opts out ofusing TDOs at 108, the TDO function and trigger functions of thetelevision may be disabled at 112. This results in appropriate flags orother indicators being set so that receipt of TDOs is ignored and/orannouncement triggers are ignored. The initialization phase orconfiguration phase is exited at 120.

However, if the viewer wishes to utilize the TDO functionality of theirtelevision set (or other television receiver device), the process setsappropriate flags or other markers indicating the user preference andproceeds to 124 where an ongoing process is initiated. This processproceeds to receive TDOs as they are offered by the service provider. Inany case, TDOs are pre-delivered or delivered simultaneously withreceipt of associated content by the television receiver device at 124.The TDOs can be delivered as user data forming a part of the DTV videostream or may be delivered by the television's Internet connection orusing any other mechanism for delivery of the program. In oneimplementation, the service provider utilizes excess bandwidth todeliver the content using NRT services as defined by either a standardsbody such as the Advanced Television Systems Committee (ATSC), or by aparticular service provider or using any other suitable proprietarymechanism.

It is noted that the downloading of TDOs is an ongoing process thatoccurs whenever TDO data are transmitted to the television. So, althoughit is depicted in this process as block 124, it is to be understood thatthis is not an ordered operation that occurs only between the blocksshown in this flow chart 100. Rather, it is an ongoing backgroundoperation that occurs as the data are presented by the source of theTDOs. It is further understood that the TDO is a program that runs onthe target television receiver device and can perform any programfunction that can be devised to run on the television receiver deviceplatform, within the scope of the available functionality offered by thestandardized API defined for TDOs.

Once a TDO is delivered, assuming the TDO does not define itself as selftriggering, it remains inactive and lies in wait until a trigger objectis received. Triggers are awaited at 128. Since the triggers and TDOsare time-sensitive by association with a television program,advertisement or other event, it is the complete receipt of a triggerobject at 128, as indicated by the “yes” at 132 and the meeting of anytime constraints imposed by the trigger's data that establishes timingfor the trigger to call for the TDO to perform or carry out itsannouncement routine. This can be accomplished by either receipt of thetrigger determining the announcement time or the trigger object maycontain a later announcement time or times. This announcement may be assimple as display of an icon for a prescribed period of time in aprescribed location of the TV screen or it may be a more complexannouncement routine such as display of an animation on the screenand/or an audio announcement. This announcement is carried out at 136.

If the viewer elects to respond to this announcement and interact withthe TDO, he or she may elect to do so at 140 by carrying out a usercommand (either a standard command or a command as instructed in theannouncement) at 144. If the user elects not to interact with the TDO,the announcement will disappear after a prescribed time or the user maydismiss the announcement by action of the remote controller at 140 toreturn control to block 128 where the next trigger is awaited.

Once the user elects to interact with the TDO at 140 and 144, the TDO islaunched by the combination of the user command and the presence of theTDO and trigger, provided all actions are taken prior to expiration ofthe TDO as prescribed in the trigger's data. The user may then interactwith the TDO at 148 in whatever manner is appropriate to the particularTDO's functionality. Once the user is done with the TDO at 150, controlreturns to 128 where the process awaits receipt of the next trigger (forthis or another TDO stored in memory). Note that as previouslymentioned, during this entire operation other TDOs may be being receivedby the television receiver device (e.g., television or STB), initializedand stored.

Any of the above processes and variations thereof can be carried out ona television receiver device such as a television set or set top boxusing a programmed processor or hardware equivalent. One basicimplementation is depicted in FIG. 3 as television receiver device 200.Device 200 has one or more central processor units (CPU) 210 with anassociated bus 215 (or multiple buses) used to connect the centralprocessor unit 210 to memory and storage represented as 220 in a knownmanner. As TDOs and triggers are received, they are stored to the memoryand storage 220. A display interface 240 is provided to either supply anoutput for an external display or, in the case of a television set, todirectly interface to an integral display 20. The television device 200includes a television receiver/tuner 250 for receiving televisionsignals including NRT data from an over the air broadcast or cable orsatellite source. In some instances, television device 200 may also oralternatively include a network connection 260 for receiving televisionprogramming and NRT data including TDOs and triggers via the Internet,for example using Sony Corporation's Bravia™ Internet Video Link (BIVL™)which may be coupled to a local area network (LAN) and/or wide areanetwork (WAN) and/or the Internet. In order to receive signals such asinfrared (IR) or radio frequency (RF) remote controller signals, aremote controller receiver 270 is interfaced to the system so that theuser can initiate commands to start the visual screening test and tocarry out the test function using a keypad of the remote controller 30as shown.

Thus, a method consistent with certain implementations involvespre-delivering a triggered declarative object (TDO) to a televisionreceiver device that carries out a programmed routine when useractivated; the TDO including an announcement definition that defines anannouncement that announces presence of the TDO to the at theannouncement time and an icon or animation that is used in theannouncement and timing data that defines a time during which the TDOmay be user activated and a screen location for display of at least aportion of an image in the TDO; initiating the TDO; delivering one ormore trigger objects associated with the TDO to the television receiverdevice, the TDO including metadata that defines: an announcement timethat defines at least one time at which an announcement of the TDO is tobe made, a screen location for the announcement, and announcing thepresence of the TDO when the announcement time is reached; receiving asignal from a user by activation of a remote controller commandresponsive to the announcement indicating that the user wishes tointeract with the TDO; and responsive to the signal from the user,launching the TDO.

Another method involves pre-delivering a triggered declarative object(TDO) to a television receiver device that carries out a programmedroutine when user activated and includes an announcement definition thatannounces presence of the TDO to the at the announcement time;delivering one or more trigger objects associated with the TDO to thetelevision receiver device, the trigger object including data thatdefines an announcement time at which an announcement of the TDO is tobe made.
